External firewire controllers and cases?

macrumors regular

I've run out of space on my hard drives and physical space in my PowerMac.

I've been checking out eBay and there are some nice 4 bay cases with firewire support. They are about £80 and I'm sure I could do the same job for much less.

Problem is, I don't know where they get the parts. I'm not so worried about the case as it's going to be hidden anyway, so I could use a bog standard PC one but the small ones are nice. Does anyone know where they get these cases?

More importantly, the firewire controller. Basic IDE to firewire (if it supports up to 4 drives that would be cool) but 2 is good. Something that will support 250GB drives would be good also. Anything that supports SATA or has some sort of RAID controller for RAID5 or even FW400/800 earns bonus points.
